All that is needed are some simple materials, most of which can be found around the home or school and in a toy store. Students will then be ready to investigate gravity, friction, electrical charges, and more. Includes many ideas for science fair projects.  (less)

to conventional institutional contexts. The approach adopted here makes a detailed analysis of research findings derived from experiments involving pupils, students and teachers in the field. Clear guidelines are laid down for the development and evaluation of sequences, drawing attention to critical details of the practice of teaching that may spell success or failure for the project. Five sequences illustrate the discussion with the following topics: contact, friction and propulsion, pressure in fluids, superposition of electric fields, superposition of coherent waves and optical imaging, and colour phenomena. This all feeds into a discussion of sequence evaluation procedures, underlining the vital importance of teachers' reactions to the detailed aspects of practice proposed to them.  (less)
